IMPROVEMENT IN PIPE-TONGS.

Specification forming part of Letters Patent No. 59,582, dated November13, 1866.

To all whom 'it may concern:

Be it known that I, MosEs H. FREEMAN, oi' Somerville, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in Pipe-Tongs; and I do hereby declare the same to be fullyde scribed in the following speciiication, and represented in theaccompanying drawings, of which- Figure lis a side view of them. Figs. 2and 3 are edge views of their two jaw-levers as separated from oneanother.

In the said drawings, A and B are the two jaw-levers ot' the tongs, thefirst one being provided with a hook-jaw, a. The second-viz., B-has atoot-11j aw, b, the forms of such levers and jaws being as represented.There projects from the base of the jaw b a tooth, o, which, when thelevers are crossed on one an other, engages with one of'a series, d, ofnotches made in the adjacent edge of the hookjaw lever, or arrangedtherein as shown in the iigures. Aclasp, e, formed as shown in Figs. land 3, extends from the lever B and projects over the lever A, it beingsimply to keep them together.

By setting' the tooth c in either of the notches of the series d weconstitute it the fulcrum of the two levers, and by means of the notcheswe can adjust the tooth-j aw nearer to or farther from the hook-jaw, asoccasion may require.

The proper position of the tooth o for adjusting the jaws to pipes orrods of different diameters may be indicated by figures ordesignating-marks engraved opposite the various notches of the series.

The two levers may be separated by drawing the hoolclever, or thatmarked A, lengtlr wise from between the tooth o and the clasp c of thelever, or that marked B. Thus it Will be seen that the levers can easilybe taken apart when it may be desirable to sharpen or grind the edge ofthe tooth '1).

I do not claim a pipe-tongs made with one jaw adjustable relatively tothe other 5 nor do I claim a pipe-ton gs made as represented intheUnited States Patent No. 49,424, as with my pipe-tongs I have no slotextending through one of its levers, whereby the same is weakcned; but Ihave the clasp e, the tooth c, and thejaw b to project from one side ofthe lever B, they avoiding the necessity of a slot and enabling thehandles to be made large and strong.

What I claim is- The arrangement of the clasp e, the tooth o.
